This is a 220V single-phase voltage input frequency converter to drive a three-phase motor (be sure to convert the connection method to a T-triangle type). Four-digit digital tube display, output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz. Suitable for motors below 750W, the maximum output power is 1100W. Features: This is an input frequency converter 220V single-phase voltage to drive a three-phase motor (be sure to convert the connection method to a triangle T type). Four-digit digital tube display, you can see the data clearly. /> Support display radiator temperature value, current current value, DC main voltage value, motor speed, operating frequency value Output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz. The frequency converter can arbitrarily change the V/F curve by adjusting the V/F compensation frequency and voltage to frequency ratio. By setting the maximum value of the V/F curve, depending on the load situation, to maximize the efficiency of using electric energy, reduce motor heat, prolong the life of the motor and frequency converter. Low frequency high torque, 220V single-phase input, 220V three-phase output, energy saving and electricity saving. Overheating and overvoltage protections.
